android - 在显示 DialogFragment 时禁用基础 View 上的触摸事件

Question

我有一个 PreferenceFragment，当我设置所有需要的东西时，我会显示一个 DialogFragment 信号加载进度。问题是，如果我点击底层 fragment 中的首选项元素，点击事件仍在处理中。

有没有办法在我的 DialogFragment 显示时禁用事件？

我的 DialogFragment 是从 PreferenceFragment 本身构建和启动的:

 final DialogFragment fragment = new DialogFragment() {
                @Override
                public Dialog onCreateDialog(final Bundle savedInstanceState) {
                    final Dialog dialog = new AlertDialog.Builder(getActivity())
                            .setTitle(R.string.dialog_hide_user_title)
                            .setMessage(R.string.dialog_hide_user_summary)
                            .setPositiveButton(R.string.dialog_hide_user_confirm_button, new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(final DialogInterface dialogInterface, final int i) {
                                    callback.onPositiveClick();
                                }
                            })
                            .setNegativeButton(R.string.cancel_button, new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(final DialogInterface dialogInterface, final int i) {
                                    callback.onNegativeClick();
                                }
                            })
                            .create();
                    dialog.setCanceledOnTouchOutside(false);
                    return dialog;
                }
            };
fragment.show(getFragmentManager(), "test");

尝试

setCancelable(false);
dialog.setCanceledOnTouchOutside(false);

希望这有帮助:)

完整代码:

final DialogFragment fragment = new DialogFragment() {
                @Override
                public Dialog onCreateDialog(final Bundle savedInstanceState) {
                    final Dialog dialog = new AlertDialog.Builder(getActivity())
                            .setTitle(R.string.dialog_hide_user_title)
                            .setMessage(R.string.dialog_hide_user_summary)
                            .setPositiveButton(R.string.dialog_hide_user_confirm_button, new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(final DialogInterface dialogInterface, final int i) {
                                    callback.onPositiveClick();
                                }
                            })
                            .setNegativeButton(R.string.cancel_button, new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(final DialogInterface dialogInterface, final int i) {
                                    callback.onNegativeClick();
                                }
                            })
                            .create();
                    setCancelable(false);
                    dialog.setCanceledOnTouchOutside(false);
                    return dialog;
                }
            };
fragment.show(getFragmentManager(), "test");
